USA observing CPR and AED Awareness Week from June 1-7, to save lives from Cardiac Arrest

The month of June is designated to raise awareness for the practical purposes and training of CPR & AED

Back in 2007, the American Heart Association, The American Red Cross, and the National Safety Council joined forces and worked fervently to assign one week of the year for CPR & AED Awareness. By December 13 2007, Congress declared that the first week of June will be recognized as CPR & AED Awareness week.

Unfortunately for the people who worked so hard to designate one week of the year to raise awareness on these two rescue tactics, the first week of June coincides with a nationally recognized holiday; Memorial Day. They have taken it upon themselves to recognize the month of June as CPR & AED Awareness Month, as opposed to just using the first week to recognize such an important topic.

The purpose of raising awareness of this first aid training tactic is simple; to save lives. According to the American Red Cross, cardiac arrest is the one of the main causes of death in adults. These sudden cardiac arrests typically happen in homes. The mission of raising awareness is also to ensure that at least one person in every household has received CPR & AED training and can properly aid anyone who may need that specific medical attention.

CPR stands for Cardiopulmonary Resuscitation. It is a rescue technique that one individual applies to another who is suffering from cardiac arrest. It is a series of actions that includes compressing on an individual’s chest and breathing air into their lungs. The goal is to ensure that a person’s blood circulation and oxygen in their body stay at functioning levels.

AED stands for Automated External Defibrillator. An AED is a machine that you can find attached to walls in many public locations. The defibrillator is used in very serious situations. When used, it restores an individual’s electrical signals to their heart. In these serious situations, if the AED is not used it could result in death or incapacitation.

The importance of CPR & AED is very blatant for anyone to see. It must be noted that these life saving tactics cannot be properly maneuvered if one has not been trained to do so. The attention CPR & AED Awareness Week/Month receives is beneficial to all. Many CPR/AED classes are available for people to take, and information is obtainable. Local events are typically hosted for the awareness week, and The American Heart Association encourages you to look into classes. The AHA also has free printable documents, which you can use to spread the word about CPR & AED Awareness Week in your very own community.

NASA to Send Organ-on-Chips To Test Human Tissue Health in Space

Called a micro-physiological system, a tissue chip needs three main properties

NASA is planning to send small devices containing human cells in a 3D matrix — known as tissue chips or organs-on-chips — to the International Space Station (ISS) to test how they respond to stress, drugs and genetic changes.

Made of flexible plastic, tissue chips have ports and channels to provide nutrients and oxygen to the cells inside them.

The “Tissue Chips in Space” initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth, NASA said.

“Spaceflight causes many significant changes in the human body,” said Liz Warren, Associate Program Scientist at the Center for the Advancement of Science in Space (CASIS) in the US.

“We expect tissue chips in space to behave much like an astronaut’s body, experiencing the same kind of rapid change,” Warren said.

The US space agency is planning the investigations in collaboration with CASIS and the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH).

Many of the changes in the human body caused by microgravity resemble the onset and progression of diseases associated with ageing on Earth, such as bone and muscle loss. But the space-related changes occur much faster.

That means scientists may be able to use tissue chips in space to model changes that might take months or years to happen on Earth.

This first phase of Tissue Chips in Space includes five investigations. An investigation of immune system ageing is planned for launch on the SpaceX CRS-16 flight, scheduled for this year.

The other four, scheduled to launch on SpaceX CRS-17 or subsequent flights, include lung host defense, the blood-brain barrier, musculoskeletal disease and kidney function.

In addition, four more projects are scheduled for launch in summer 2020, including two on engineered heart tissue to understand cardiovascular health, one on muscle wasting and another on gut inflammation.

Also called a micro-physiological system, a tissue chip needs three main properties, according to Lucie Low, scientific programme manager at National Center for Advancing Translational Sciences in the US.

“It has to be 3D, because humans are 3D,” she explained.

“It must have multiple, different types of cells, because an organ is made up of all kinds of tissue types. And it must have microfluidic channels, because every single tissue in your body has vasculature to bring in blood and nutrients and to take away detritus,” she added. (IANS)
